Monitoring Pool/Spa Area for Safety

The M1 system can detect that someone has entered the pool/spa area and provide audible notification.  Contacts on doors, entrance gates, and outdoor motion sensors are used to monitor the area around the pool or spa.  When someone enters the pool/spa area, the M1 can beep keypads, display a message on the keypad, and provide a voice announcement that will repeat until acknowleged.
 

The door contacts and motion sensors may be hardwired to the control or an M1XIN Input Expander, or may be wireless.  The M1 Gold and EZ8 systems are compatible with the following wireless receivers:


ELK-M1XRFTW - 
144 Zone Wireless Transceiver - Supports ELK Two-Way Wireless Sensors
ELK-M1XRF2H - 144 Zone Wireless Receiver - Support Honeywell 5800 Series One Way Transmitters
ELK-M1XRF2G - 144 Zone Wireless Receiver - Supports GE Crystal Transmitters


The M1 or EZ8 system monitors the zones around the pool or spa and makes an announcement inside the home if a zone is violated.  A miscellaneous voice message is programmed to annnounce a message such as "Pool Area Alert" or "Warning Someone Is In The Pool Area"



A rule is written to announce this voice description when the zone is tripped or violated.  Also, the keypad will beep and “Pool Alert” will be displayed on the keypad.  Two phantom or unused outputs are used; one phantom output is turned on for 20 seconds to provide a timer for repeating the message.  Another unused output is turned on, providing a flag that can be reset when the alert is acknowledged at the keypad

WHENEVER Pool Motion (Zn 10) BECOMES NOT SECURE
          THEN ANNOUNCE Micellaneous 1 (vm239)
         THEN DISPLAY “Pool Alert” IN Area 1 (Area 1) INDEFINITELY, BEEP
    THEN TURN Output 100 ON FOR 20 SECS
    THEN TURN Output 101 ON

A similar rule should be written for each door, motion sensor, and gate that is being monitored  A second rule is needed to repeat the voice message.

WHENEVER Output 100 STATE IS TURNED OFF
     AND OUTPUT 101 STATE IS ON
          THEN ANNOUNCE Micellaneous 1 (vm239)
    THEN TURN Output 100 ON FOR 20 SECS

A rule is used to make this announcement, instead of using the chime feature.  This is because the chime feature may be disabled to prevent announcements from other zones.  The announcements from the monitored pool area zones should be heard even if the chime has been disabled.

The rule below allows the user to silence the alert and clear the keypad with the F4 key.  If desired, the F4 key can be programmed to require a valid code entry.

WHENEVER F4 KEY ON ANY KEYPAD ACTIVATES
    AND OUTPUT 101 STATE IS ON
         THEN TURN OUTPUT 101 ON FOR 2 SECS
         THEN CLEAR ALL PREVIOUSLY DISPLAYED MESSGES IN Area 1 (Area 1)


Temporarily Disable Monitoring When Pool/Spa Is In Use

The customer may desire to disable the pool/spa announcements while in use.  However, the system must automatically reset, allowing the announcements to resume, in the case that the customer forgets to re-enable pool/spa area monitoring.

Pool/Spa area monitoring can be disabled/enabled using an F key (F4 in this example).   The rule below toggles an unused output (Output 102 in this example) when the F4 key is pressed on Keypad 2, which is located near the patio door that leads to the pool/spa area.  The state of Output 200 determines if the warning announcements are enabled or disabled.  Also, a counter (named Pool Counter in this example) is set to 300, which will be used as a timer.

WHENEVER F4 KEY ON KEYPAD2 ACTIVATES
     AND OUTPUT 101 STATE IS OFF
          THEN TOGGLE Output 102
          THEN SET Pool Counter (Counter 1) TO 300

The rule written to give the pool alert must be modified to only make the announcement if Output 102 is off.  This can be accomplished by adding an AND statement to the rule as shown below in bold.

WHENEVER Pool Motion (Zn 10) BECOMES NOT SECURE
    AND OUTPUT 102 STATE IS OFF
          THEN ANNOUNCE Micellaneous 1 (vm239)
         THEN DISPLAY “Pool Alert” IN Area 1 (Area 1) INDEFINITELY, BEEP
    THEN TURN Output 100 ON FOR 20 SECS
    THEN TURN Output 101 ON

Anytime a monitored zone becomes not secure and Output 102 is on, the Pool Counter is set to 300.  A rule similar to the one below must be written for each monitored zone.

WHENEVER Pool Motion (Zn 10) BECOMES NOT SECURE
     AND Output 102 STATE IS ON
         THEN SET Pool Counter (Counter 1) TO 300

The rule below decrements the Pool Counter by 1, every second if Output 102 is on.

WHENEVER EVERY 1 SECONDS
     AND Output 102 STATE IS ON
     AND Pool Counter (Counter 1) IS GREATER THAN 0
          THEN SUBTRACT 1 FROM Pool Counter (Counter 1)

As long as motion is being detected in the pool/spa area the counter will continually be reset to 300 (300 seconds = 5 minutes).  If the Pool Counter ever reaches 0, Output 102 will be turned off, which will allow warning messages to be announced again.  To allow more or less time before the “reset” occurs, simply modify the number that the counter is set to when motion is detected.

WHENEVER Pool Counter (Counter 1) CHANGES TO 0
          THEN TURN Output 102 OFF

The F key illumination event can be programmed to follow the state of output 102 to give the customer visual indication when the Pool/Spa alert is enabled or disabled. 



You can also program a voice message to be announced when the pool alert becomes enabled or disabled.  For example, 2 miscellaneous messages are programmed.  One says “Pool Alert Activated”.  The other says “Disable Pool Alert”.  The rules below will announce the appropriate message when the state of the unused output changes.

WHENEVER Output 102 STATE IS TURNED OFF      
     THEN ANNOUNCE Miscellaneous 2 (vm240)

WHENEVER Output 102 STATE IS TURNED ON
          THEN ANNOUNCE Miscellaneous 3 (vm241)
